pix 515E netbios broadcast between interfaces and ip address helper

Answered Question
Oct 30th, 2008

1) If the ACL between the 2 interfaces is "permit all", does it allow the broadcasts (like netbios) to be relayed to the other interface?

2) And does 515E have an ip address helper? I don't see any commands relating to ip address helper when I do "?".

The version of the pix is:

Cisco PIX Firewall Version 6.1(4)

Thank you

I have this problem too.

1) Pix firewalls running 6.x code will not forward broadcasts across it's interfaces.

2) Pix firewalls do have a DHCP relay function which is essentially the same as ip-helper but this was introduced in version 6.3 so it won't be available in 6.1(4) -

So for 1), is it possible to allow broadcasts to be forwarded between its interfaces?
